- Arrows
- Little killers
The brief
- Normal sudoku rules apply, i.e. each Row, Column, and 3x3 region has to contain the digits from 1 to 9 once each.
- Arrows: Digits on an arrow sum to the digit in the circle from which the arrow emerges.
- Little killer: Digits on a marked diagonal must sum to the clue outside the grid. (If there is no conflict with other rules, digits on such a diagonal may repeat.)
